T o all whom it may concern:

Be it known that I, HARRY C. S'ricxEL, a citizen of t-he United States, residing at Star Junction, in the county of Fayette and State of Pennsylvania,'have invented a new and useful Adjustable Extension. for Piano- Pedals, of which the following is a specification.

The invention relates to tension for piano pedals.

The object of the present invention is to an adjustable ex- 'improve the construction of adjustable extensions for piano pedals, and to provide a simple and practical device, adapted to be easily and cheaply manufactured, and capable of being readily applied to a piano pedal and of easy adjustment to arrange its foot-receiving portion at the desired elevation.

A lV ith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope ot' the claims, may be resorted to without departing from the spirit or sacrificing any of t-he advantages of the invention.

In the drawing Figure 1 is a side elevation of an adjustable extension for piano pedals, constructed in accordance with this invention and shown applied to a pedal. Fig. 2 is a vertical transverse sectional view of the same. Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 2. Fig. 4 is a detail perspective view of the lower end-of the tubular standard, illustrating the construction of the pedal clamp.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

1 designates an upright tubular standard, arranged at a slight inclination and extending upwardly and outwardly from a pedal 2 to support a foot-receiving plate 3 in proper position with relation to a piano 4, so that a child sitting in proper' position on. a piano stool may place its foot upon the plate 3. The tubular standard is constructed of a piece of suitable tubular meta-l, which yhas its lower portion split, and the severed portions are bent to form approximately U-shaped jaws 5 and 6, conforming to the in the accompanying configuration of the pedal 2 and consisting of curved side portions and inwardly extending horizontal portions having depending terminal lugs spaced relation and connected by a screw 9. The threaded portion of the screw extends through perforations of lugs 7 and 8 and is engaged by a nut 10, fitted against the lug 8 and engaged by the horizontal portion of the jaw 6, whereby it is held against lateral movement. The screw has an extended neck portion 11, and is suitable head 12. The neck portion, which is of greater diameter than the threaded portion, forms a shoulder 13 for engaging the lug 7, and the head is off-set from the lug by the extended neck 11 a suiiicient distance to enable itjto be readily operated. The standard is equipped with a collar 14, encircling the standard contiguous to the jaws and adapted to prevent the tubular standard from splitting beyond By this construction, the device may be tightly clamped to a pedal without marring or otherwise injuring the same.

The foot plate, which is horizontal, is provided withv an integral stem` 15, slidable within the tubular standard and rounded to fit the interior of the same, and provided at one side with a flat face 1G having teeth 17, shouldered at the lower ends, as clearly illust-rated in Fig. 2 of the drawing, and adapted to be engaged by a catch 18, constructed of spring metal and consisting of an inclined portion 19 and a horizontal portion 20. The inclined portion, which extends upwardly and inwardly from the exterior of the tubular standard, is secured at its lower end to the same by a rivet 21, or other suitable fasi tening device, and it projects through .a slot 22 inthe upper portion of the standard. The horizontal portion 20 of the catch extends outwardly from the upper end of the inclined portion, and the angle formed by the two portions of the catch engages the toothed face of the stem 15, wherebyA the foot plate is secured in its adjustment. The catch also operates to hold the stem against rotary movement within the standard and maintains the foot plate in proper relation with the pedal. The outer end of the horizontal portion of the catch is curved upwardly and inwardly to form a foot operating portion 23, adapted to' be readily engaged by the foot to withdraw the catch from the teeth of the stem to permit the foot-receiving portion 7 and 8, arranged in' provided with a.

the clamp.

to drop. The foot-receiving portion is adapted to be readily lifted'by the foot, the spring catch permitting such upward movement of the stem.

Having-thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. An adjustable extension for piano pedals comprising a tubular stem split at the lower end, the severed portions being flattened and bent into approximately U-shaped pedal-engaging jaws having horizontal inwardly extending bottom portions and depending terminal lugs located at the inner ends ot' the said bottom portions, a screw piercing the lugs and having a shoulder engaging one of the lugs, a nut engaged by the screw and fitting against the other lug and having its upper edge engaged by the horizontal portion of the contiguous jaw, whereby it is held against rotary movement, a collar encircling the standard contiguous to the upper Aend ot' the piano, a foot plate having l a stem slidable within the tubular standard7 and means mounted on the standard and en- 2. An adjustable extension for piano tubular stan dard and rounded to fit the same,

said stem being also provided with a Hat ace and having teeth thereat, and a catch constructed of spring metal and consisting of an inclined portion secured at its lower end to .the exterior oi' the tubular standard and extending upwardly and inwardly through the slot of the saine, and a horizontal portion extending outwardly from the upper end of the inclined portion and having its outer terminal portion extended upwardly and inwardly to form a foot operating portion, the inclined and horizontal portions of the catch forming an angle, which engages with the teeth ofi the stem to secure the foot plate in its adjustment.

' InA testimony, that I claim the foregoing as my own, I have hereto atiixed my signature in the presence ot two witnesses.
